Active Suspension Rhythmic Control Using Audio Frequency Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles fail to meet users' personalized entertainment requirements when stationary, lacking interactive features that enhance user experience through rhythmic movements synchronized with audio signals.
Innovation Solution
An active suspension system in vehicles adjusts its movement based on frequency signals from audio signals, enabling rhythmic actions such as jumping and pressing down, synchronized with music, using motors and dampers to alter the vehicle's height and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle remains stationary during user interaction, then safety and stability are maintained, but user entertainment requirements and personalization are not met
Solution Approach 1:
The suspension system transitions from a static state to a dynamic state by enabling rhythmic movements synchronized with music beats. The motor drives the suspension to perform periodic up-and-down motions, transforming the vehicle from a completely stationary state to one with controlled dynamic behavior that provides entertainment while maintaining overall stability through controlled, rhythmic motion rather than random movement
Solution Approach 2:
The suspension system performs periodic rhythmic movements synchronized with the beat frequency of music. The motor receives frequency signals from the audio system and generates corresponding periodic suspension adjustments, creating a rhythmic dancing effect that matches the music tempo while maintaining controlled, predictable motion patterns
2Adaptability or versatility
If the active suspension system performs rhythmic movements to provide entertainment, then user experience is improved, but energy consumption increases
Solution Approach 1:
The system applies partial action by enabling rhythmic movements only during specific entertainment scenarios rather than continuous operation. The suspension performs rhythmic adjustments only when music playback is detected and user interaction is required, rather than operating continuously, thereby reducing overall energy consumption while providing entertainment when needed
Solution Approach 2:
The system changes operational parameters by adjusting motor power output based on music frequency signals. The motor varies its rotation speed and suspension adjustment magnitude according to the beat frequency and amplitude of the music, performing stronger rhythmic movements during high-energy music passages and reducing activity during quieter segments, thereby optimizing energy consumption according to actual entertainment needs
